STARTING AND OPERATING 221 If you need snow tires, the recommended size for the front and rear tires is the same size as the original equipment front tires. This size tire on the rear allows the use of tire chains on the rear wheels. Selection of this size tire also requires the purchase of two additional wheels with the same size specification as the original equipment front wheels. Snow tires may have a lower speed rating than factory equipped tires and may not match the maximum vehicle speed. Snow tires should not be operated at sustained speeds over 75 mph (120 km/h). TIRE ROTATION RECOMMENDATIONS Tires on the front and rear axles of vehicles operate at different loads and perform different steering, driving, and braking functions. For these reasons, they wear at unequal rates, and tend to develop irregular wear patterns. These effects can be reduced by timely rotation of tires. The benefits of rotation are especially worthwhile with aggressive tread designs such as those on all season type tires. Rotation will increase tread life, help to maintain mud, snow, and wet traction levels, and contribute to a smooth, quiet ride. Follow the recommended tire rotation frequency for your type of driving found in the "Maintenance Schedules" Section of this manual. More frequent rotation is permissible if desired. The reasons for any rapid or unusual wear should be corrected prior to rotation being performed. 5
